Note: The PCM signals (PCMADI and PCMADO) of the ADPCM transcoder can be assigned to  
time slot 1 or 2.  
The PCM signals (PCMLNI, PCMLNO, PCMACI, and PCMACO) of the echo canceler can  
be assigned to one of the time slots 1 to 4.  
The ADPCM signals (IR and IS) of the ADPCM transcoder are always assigned to time slot  
1.
